Specification of Letters Patent.

Patented April '7, 1908.

Application filed September 17, 1907. Serial No. 393,302.

To all whom it may concern:

Be it known that 1, JOHN E. FLYNN, a citizen of the United States,residing at Austin, in the county of Potter and State of Pennsylvania,have invented certain new and useful Improvements in Grab-Hooks; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to grapples; and it consists of a grab-hook orlogging-dog constructed as hereinafter fully described and claimed.

In the drawings, Figure 1 is a side view of the grab-hook. Fig. 2 is afront edge view of the grab-hook.

A is the shank of the grab-hook which is provided with a longitudinalslot 1) which extends for about one half of the length of the shank andin its upper end portion. B is a curved hook at the lower end of thesaid shank. This hook is provided with a narrow web C under its pointedend and middle portion, so that flanges c are formed along its upperedge for the purpose of strengthening it. The narrow web C has a sharpedge d at its outer end portion under the point of the hook, and thisconstruction enables the hook to be driven intothe log with facility andwithout splitting the log. The upper part of the shank is provided witha sharp blade E which projects partway over the hook, and which is alittle longer than the slot 1). The blade E is longer than the distancebetween the lower end of said blade and the part of the hook underneathit.

F is a portion of a chain or other suitable draft attachment which isslidable longitudinally in the slot 1). The dotted line 9 indicates thesurface of the log, and the hook and the blade are driven into the logas indicated in the drawing, so that the surface of the log'bearsagainst the upper part of the shank at the base of the blade and againsta shoulder h at the end of the web C. A space i is left at the lowerpart of the shank between the said shank and the surface of the log, anda bar or any convenient tool is inserted in this space for the purposeof extracting the grab-hook from the log when desired. The grab-hooksare preferably used in pairs, another similar grab-hook being attachedto the other end portion of the chain or draft attachment. A number ofpairs of logs are coupled together, with two dogs and a chain betweeneach log, and these logs are arranged side by side as they float onwater, and each log is free to move to a limited extent endwise. Whenany log is moved so that its chain is pulled against the outer or upperend of the slot 6 at the end of the shank, there is no tendency to pullout or disconnect the hook. When the lo is pulled in the reversedirection the chain i slides in the slot 1) so that it engages with thebottom end of the slot 1) at the middle part of the shank. There is thena slight tend ency to disenga e the hook, but as the chain has only onehalf the leverage it would have if it were connected to a hole at theouter end of the shank, the hook B is not torn from the log.

What I claim is: v

1. A grab-hook provided with a shank having a hook at one end and alongitudinal slot in its other end portion, and having also a bladeprojecting from thesaid shank on one side of the said slot, incombination with a draft attachment which is slidable longitudinally inthe said slot.

2. A grab-hook provided with a shank having a hook at one end and alongitudinal slot in its other end portion, said hook being providedwith a sharp web at its lower part and flanges extending along its upperedge, and the said shank being also provided with a blade which projectsfrom one-side of it adjacent to its said slot, in combination with adraft attachment which is slidable longitudinally in the said slot.

3. A grab-hook provided with a shank having a hook at one end and alongitudinal slot which extends from its middle portion to its outer endportion, and having also a blade which projects from the middle and endportions of the said shank, in combination with a draft attachment whichis slidable longitudinally in the said slot to vary the leverage on thehook according to the direction of draft.

In testimony whereof I have'affixed my signature in the presence of twowitnesses.
